Background

Biospeckle laser technique is an emerging non-destructive, quality detection tool used for the evaluation of biological samples. It is rapid, easy to operate and economical, and assures the quality and safety of the fresh produces.

Scope and approach

The biological activity of the materials is altered due to the contamination, damages, maturation, etc. Hence, these factors can be non-destructively analyzed by the biospeckle method combined with the numerical processing techniques. Several qualitative and quantitative methods namely, Fujii, Absolute Value Difference, Inertia Moment, Generalized Difference, etc have been developed for effective biospeckle analysis. Major applications of this tool include identification of bruises, maturation and ripening changes in fruits and vegetables, meat quality detection, seed viability analysis, and detection of fungal colony infection.

Key findings and conclusions

Even though the technology has got a wide range of applications, there are some limitations and challenges that hinder its large scale adoption. The impediments such as external noise and interferences have to be addressed to obtain accurate results. There is a need for the development of standardized procedures for conducting the analysis. This review mainly discusses the various applications of biospeckle laser technique as a non-destructive tool in quality and safety analysis, the methods adopted for the evaluation process, the relation between biochemical changes and biospeckle and the various challenges thereof.

生物散斑激光技术–一种用于食品质量和安全检测的新型无损检测方法

背景

生物散斑激光技术是一种新兴的无损质量检测工具，用于评估生物样品。它快速，易于操作且经济，并确保了新鲜农产品的质量和安全性。

范围和方法

由于污染，损坏，成熟等原因，材料的生物活性会发生变化。因此，可以通过生物斑点方法结合数值处理技术对这些因素进行无损分析。已经开发了几种定性和定量方法，即藤井（Fujii），绝对值差，惯性矩，广义差等，以进行有效的生物斑点分析。该工具的主要应用包括跌打损伤的识别，水果和蔬菜的成熟度和成熟度变化，肉质检测，种子生存力分析以及真菌菌落感染的检测。

主要发现和结论

尽管该技术具有广泛的应用范围，但仍存在一些局限性和挑战，阻碍了其大规模采用。必须解决诸如外部噪声和干扰之类的障碍，以获得准确的结果。需要开发用于进行分析的标准化程序。这篇综述主要讨论了作为非破坏性工具的生物斑点激光技术在质量和安全性分析中的各种应用，评估过程所采用的方法，生化变化与生物斑点之间的关系以及它们所面临的各种挑战。
